Abstract

During the period of IPv6 transition, both ISP and ICP (Internet
Content Provider) care about user's experience in dual-stack network.
They hesitate to provide IPv6 to their users due to the fear of poor
IPv6 performance. Network-based Happy Eyeballs (NHE) is proposed in
this memo as a approach to provide better connectivity to end users
by doing accurate measurement and comparison on IPv6/IPv4 performance
on the network side other than client-side Happy Eyeballs (HE)
([RFC8305]). It works independently with client's adoption of HE.
